To ALL WHoM rr MAY ooNonRN:

Be it known that vI, JOHN C. FISH, of the townand county of Barnstable,and State of ll/Iassachusetts,y

have invented a new andimproved Device for Oiling Rotating Bodies; and Ido hereby declare that the following, taken'in connection with thedrawings which accompany and formpart of this'specication', is adescription of my invention sufficient to enable those skilled inthe artto practise it.

l This inventionl illustrate'herein in itsl application to the hubs ofcarriage-wheels, though it may be applied in asimilar 'nianner and withsimilar results to other bodies rotating or moving on or about shafts,axles, or pins. In the drawings l Y l I 4Fi ure shows in sectionalelevation a. wheel for a Wa on or carriafre, havin a lied to its hub m gg e g PP Y y improved oiling device.

This consists of a reservoir,.a, provided with a tube, c, extendingthrough it and secured therein, said tube having two openings from itsside into the body of the reservoir, an upper one at d, and a lower oneat c. The top and bottoni of..this tube c are open, the bottomconnecting with a tube,f, set into the hub g and the box it of thewheel, and the top being provided with the threads of a nut. Closelyfitting in the tube c is a tube, e, closed at its top,- and providedwith 'screiv-th`reads, which, kttingthe nntltbreads at the top of tubec, canse tube t' to rise and fall therein whenever tube is rotated. Inthe sides of tube z' are three openings, two of which, nino, correspondwith the openings e in the tube e when the tube t' is-raisedsuliicientlyin tube c for tbedppeiopening o in' tube z' to communicatewith the' atmosphere. In the tube between its openings n and'o, preferto locate a plug orv partition for a. purpose tojbe hereafter referredto. In the reservoir there is a l removable screw-plug, 70, serving toclose the orifice through which the supply of oil is delivered tothe'reservoir.

rEhe-tube z' is provided with means 'oy which it can be rotatechand thusraised and lloweie'ed in tube c by the employment of a wrench orscrew-driver. If the reservoir is filled orl partly iilled with oil, andthe parts are in the position shown in the drawing, it will be obviousthat oil must gravitate upon the axle m from the reservoir, as air willflow through the'openin'gv, tube z', openings o, and d, to supply theplace ofthe oil flowing upon the surface to be lubricated. But if thetube z' is sciewed down into tube c, so that the opening v no longeradmits the passage of air, the flow of oil will be stopped, as the oilwill not run out of the reservoir and producen vacuum therein. The'oilwill also be prevented from ilowing, because the passages 1t and e willno longer open into each other, the solid metalof the tube i closing thepassage e.. The purpose of the plug or--partitio'n"beforc v mentioned asinA the tube z', is to act as the piston of a syringe in forcing the oilbefore it upon the siiiface to be lubricated, as the tnbe t' is'movedinwards into tube c. The joint between' the tube c in the reservoir andthe tubef in the hub may be made, as in lig. 1, by a Washer of suitablelyielding material, or by a thimblc, as Seen in fig. 2, the thiinbleenclosing the adjacent ends ofc-the tubes c mdf. In applying this oilingdevice to carriage-wheels, the size, shape, and locution of thereservoir may be varied to suit circumstances, and in some instances itmaybe wholly embedded in the wood of the hub. An amount of lubricatingmaterial can bc easily contained in the reservoirs of a set. of wheelssuilicient to last a carriage in constant use for several weeks; no oilis lost or wasted, neatness is preserved, andthe oiling is easilyeffected by thc simple operationvof rotating the tubos z', instead of bypropping up cach end of each axle and removing the wheels therefrom-iuthc usual way. y

I claim a lubricating apparatus, constructed of a reservoir in which islocated the tube @,provided with openings as described, and with aperforated movable tubo, t', operating substontiallyus described.
